DMC developed an end-of-line test station for an automotive sensor manufacturing line. This system integrated a wide range of instruments in order to program and test the automotive sensors before they were integrated into the vehicle.

DMC created this system to program and test an automotive sensor at the end of a manufacturing line. The system measures several parameters on the part, determines the optimal values, and programs offsets into it. The part is then tested by sweeping a magnet in front of the sensor, resulting in a sine and cosine wave pattern which is analyzed to determine whether the part should pass or fail. Once the part has been tested, data pertaining to the part is logged to a database for reporting and analysis.
